I also need help with this as well.
I have done more than 100k wager after Ive received the mail, but got no bonus. Im still waiting for my host + support to help.
Im %100 confident that the wager is done.
I can also prove this by sharing my statistics as well. I believe there is a time problem in this, they probably calculated the wager after several hours this email was sent. hope they resolve the issue.
